I've looked at the site and i agree with vishkanya. I think they are fake. The dates aside which on their own are highly suspicious, look at the similarity of the writing - Most start with "I have worked" and the second sentence is " I have found"' . All the reviews state the word "client" whereas there are so many alternatives ie customer, buyer, purchaser etc.
Both the dates and the language/choice of words show that they have been written by one person most likely from academic knowledge.
